BMW 325i Problem

Rolled down rear window on my BMW 325i and hear a loud pop like breaking glass. Opened the door up and sure enough it was the window regulator that was broken on my car with 46K miles. BMW should be forced to repair this under a recall.
Rear window regulator broke in the down position. You can hear the motor trying to move the window when you hit the button, but nothing happens. Part had to be replaced at the expense of $240

Just put window down today passenger side window will not go up. Bmw should recall the junk materials they used in such a pricey vehicle. Hardly ever put my windows down so cannot blame it on overuse.
